Issue with Fingerprint Sensor after Overnight Battery Drain – Samsung S21 FE
Last night my Galaxy S21 FE was at around 60% battery when I went to sleep. By morning, the battery had fully drained, and the phone would not power on. I had already turned off everything and closed all apps before sleeping, so this was unusual.
When I plugged in the charger in the morning, the phone powered on at 1% battery. However, I noticed that the fingerprint sensor had stopped working. When I went into settings to set it up again, it showed an error message advising me to visit a service centre.
At the Samsung Service Centre, they attempted to calibrate the fingerprint sensor, but the process kept getting stuck. They told me the only option is to perform a full software installation, which would erase all my data. Since I didn’t want to lose my data, I came back without proceeding.
Has anyone else faced a similar issue? Is there any way to fix the fingerprint sensor without losing all data.
